Windows & Energy Efficiency

Spring has sprung and the winter chill is giving way to hot sun. Many people know that drafty windows can drive heating costs through the roof in the winter, but did you know the reverse is true in the warmer months? Expensive AC leaks out of poorly insulated windows can break the bank in the dead of summer.  Already have properly insulated replacement windows? The following steps will save you money this summer in addition to your new replacement windows!


Opening your windows to enjoy a spring breeze is always pleasant, but as the temperature rises opening windows can drive AC costs up. We recommend that all windows and doors are kept closed any time the AC is running. Not only will this improve cooling efficiency, but also reduce stress on your air conditioner.

AC units have an automatic system, so they emit cool air to bring the temperature to the one you set. When the temperature is reached, it shuts off. It will then turn itself back on once the temperature rises again. This system keeps costs down, the room at the right temperature, and prevents damage to the AC unit. A unit that is constantly running is more likely to malfunction, struggle to maintain the proper temperature, work harder, and consume extra energy.

Along with keeping windows closed, we recommend these energy saving improvements to keep your home cool and your costs down:

  • Install window shades, drapes, or blinds
  • Apply window film
  • Weather-strip your windows
  • Get cell shades

Energy Efficient Factors

When deciding what type of window you need to replace old, drafty windows, there’s a few things to know about energy efficiency. It’s important to consider their energy performance ratings in relation to climate and home design. You should also select windows with both low U-factors and low SHGCs to maximize energy savings in temperate climates with both cold and hot seasons such as Virginia.

  •         U-factor is the rate at which a window, door, or skylight conducts non-solar heat flow. For windows, skylights, and glass doors, a U-factor may refer to just the glass or glazing alone. The lower the U-factor, the more energy-efficient the window, door, or skylight.
  •         Solar heat gain coefficient (SHGC) is the fraction of solar radiation admitted through a window, door, or skylight and subsequently released as heat inside a home. The lower the SHGC, the less solar heat it transmits and the greater its shading ability. A product with a low SHGC rating is more effective at reducing cooling loads during the summer by blocking heat gain from the sun.
  •         Air leakage is the rate of air movement around a window, door, or skylight in the presence of a specific pressure difference across it. A product with a low air leakage rating is tighter than one with a high air leakage rating.

Window Design

Now that you’ve decided to save money and energy, it’s time to pick you a design! Different designs have different benefits.

  • Awning: These windows are hinged at the top and open outward. Awning windows have lower air leakage rates than sliding windows.
  • Casement: These windows are hinged at the sides. Similar to awning windows, they have lower air leakage rates than sliding windows because the sash closes by pressing against the frame.
  • Fixed: Fixed panes don’t open. These windows are airtight, but are unsuitable in places where window ventilation is desired.
  • Hopper: Hopper windows are hinged at the bottom and open inward. Like both awning and casement, they generally have lower air leakage rates.
  • Single-hung: Only the bottom sash slides upward in a single-hung window. Sliding single-hung windows have higher air leakage rates.
  • Double-hung: Both sashes slide vertically in a double-hung window. Like single-hung sliding windows, double-hung generally have higher air leakage rates than projecting or hinged windows.
